It is possible to use a Super to kill a Viola by the door and pause abuse to grab its Energy drop on G-mode exit.

Requires:

{
  "or": [
    {
      "and": [
        {
          "ammo": {
            "type": "Super",
            "count": 1
          }
        },
        "h_heatedGModePauseAbuse",
        {
          "heatFrames": 10
        }
      ]
    },
    "h_heatedGModeOpenDifferentDoor"
  ]
}

Dev note: As Violas only give small Energy, Samus is likely to lose a few Energy overall.
